Essays on Stem

Abstract:

Medicine and science had always maintained a steady flow of debates by the beginning of the 20th century with the ongoing increase of diseases, and virus mutations keeping up with the modern technology. Medicines had to be updated regularly to ensure that mutations would not influence a person’s sickness and overall health. It is common to see various medical procedures claiming that they can cure a disease or complication without the need to pay medicines regularly. One of these offerings is known as stem cell treatment, which uses stem cells to repair damage tissues or cure diseases. While the preliminary studies ...

Abstract

Stem cells research and particularly stem cell research is an area that has continually stirred up moral, spiritual and cultural dilemmas. Several arguments have been advanced both for and against stem cell research even as advances that are being made in the field of stem cell research continually evolve making it closer to becoming a widely practiced scientific application. Stem cells are widely studied because of their inherent ability to be renewed and regenerated in addition to their ability to adapt to different environments. Some of the benefits of stem cell research are: stem cells can be used in the ...

INTRODUCTION

The human body consists of tissues and organs that contain over 200 different cell types.1 these cells carry out all the functions required for viability and reproduction. It was argued long ago, that in some tissues, the differentiated cells have a shorter life span and that they are not able to self -renew.2 This led to the notion that such tissues are maintained by cells that have an extensive renewal capacity, and the ability to differentiate and generate daughter cells. These cells were termed as ‘stem cells”.2 Stem cells generate only the differentiated lineages of the tissues they reside in, ...

Healing the Future

INTRODUCTION In a diverse nation like the United States there are many ideologies, philosophies, cultural “norms,” and belief systems, it is not really surprising that people are not always going to agree. There are many legal, political, and social issues that raise ethical questions that the public cannot agree upon how best to approach and address the debated issues. One of the most heatedly debated issues that exist today is the concerns surrounding stem cell research. Stem cell research has the potential to change the field of medicine and how people are healed. However, all of that potential is ...

Besides the benefits from the research in stem cells, the research has proven to be one of the most controversial issues in the modern world. The prime concern is deciding whether its continuity is right or wrong. Many are arguing the issue of morality which involves the use of human embryos, genetic engineering, cloning and the biological impacts resulting from the research. It has spanned a strong debate in regard to its credibility in regard to ethical concerns primarily about creation, destruction and also the use of embryos. It does not stop there because of other issues raised about the species ...

INTRODUCTION

A Director at the University of Georgia Atmospheric Sciences Program posed a question during an interview with the Ebony magazine “Why African American girls May Be Left Out of the 21st Century Job Market”. The answers to the question seem to be glaring simple and complicated at the same time. African Americans, especially girls in the science, technology, engineering and mathematics (STEM), continue to record decreasing numbers careerwise. Will all the data pointing to the fact that STEM jobs in the 21st century are considered the best jobs with the top 15 emanating from any one f those fields. ...

INTRODUCTION

The debate over stem cell research, and whether or not it should be made legal, is very complicated and long-standing. Stem cell research involves investigating whether or not embryonic stem cells can be used to potentially cure a number of diseases, including Parkinson’s, Alzheimer’s, and many others. The theory is that, since stem cells are able to differentiate into any other cell in the body, that they can be used to create healthy cells where once there were cancer cells, thus treating the disease. Stem cells have already been used to repair disease-ridden tissue successfully in patients (Neel & ...

Embryonic stem cell is a crucial factor in the developmental process of a multicellular organism. Embryonic stem cells (ESCs) are derived at early stages during development and eventually give rise to all type of tissues and organs in an animal. The ES cell lines have three properties consisting of self-renewal, primary chimera formation and pluripotency [1]. Pluripotency, a key feature of ESCs, refers to the capacity of a cell to differentiate into several different types of tissues [2]. An array of cellular factors play important role in maintaining pluripotency and determining cell fate in the developmental pathway. Negative effects on these factors may ...

Stem cells have a major role in the biological processes. Because of the ability of the stem cells to divide, they are important in the development of an organism and repair of damaged tissues. Stem cells have the potential to treat degenerative diseases like diabetes, Parkinson’s and heart disease. The unique characteristics of stem cells include its ability to divide, replicate and renew themselves for long periods. They are unspecialized; thus, they can produce specialized cell types. They can differentiate into other cells. Stem cells have regenerative abilities which make it useful in therapeutic interventions. They can produce ...

INTRODUCTION:

The stem cell research has been debated ever since the birth of it. However, the categorization of the stem cell research has been defined in a wrong manner. Moreover, the media is sensationalizing the topic. This has resulted in a wrong notion that all stem cell research is unethical. This is a wrong notion of the research because there are two types of stem cell research. The adult stem cell research is ethical than the embryonic stem cell research. Adult stem cell research refers to the usage of matured cells from mature adult human being without killing the host. On the ...

Embryonic stem cells have the tendency to divide for long duration and continue to have their capacity to make all cell types within the organism. Thus they are termed pluripotent stem cells. Embryonic stem cells are obtained from embryos which are particularly obtained from eggs that have been fertilized in vitro. The embryonic stem cells are recognized by two distinctive properties – their pluripotency and their ability to replicate indefinitely. Cell culture is a procedure wherein the embryonic stem cells are grown inside the laboratory. The human embryonic stem cells are first separated by removing the inner cell mass into ...

Introduction:

Stem Cell Research has been one of the most controversial breakthroughs of science since the late 1990’s. The extraction of the human embryonic cell on that decade has made various responses in the medical field. This has opened many doors for many scientists that are highly interested in regenerative medicine. Additionally, this has also opened new debates about the ethics of the process of harvesting stem cells. There are two types of stem cell research. The first one is known as the embryonic stem cell research. The second one is named as the adult stem cell research (Shapiro, ...

According to the Merriam-Webster dictionary, stem cell is an undifferentiated cell that can generate other cells which makes up specialized organs and tissues in living organisms. Stem cells are of two major types namely; adult stem cells and embryonic stem cells. Embryonic stem cells are found inside an embryo that is in its earliest developmental stage i.e. blastocyst, these stem cells eventually give rise to the adult organisms. The adult cells helps in the regeneration of worn out tissues and are located in some of the tissues in the body of living things e.g. the intestine lining, the skin’ ...

Abstract

This paper describes and discusses the various types of human stem cells, including those in early-stage embryos (the blastocyst) and those present in adult tissue, explaining the practical uses of the various types in the medical field, where stem cells can be used to repair damaged tissue and organs. Although the adult stem cell types offer fewer possibilities for medical applications than the embryonic type, their use is less ethically controversial because it does not require destruction of a living albeit very early stage embryo. Research into stem cell applications is finding improved techniques. These include the treatment of acute ...

The adult stem cells refer to the undifferentiated cells that are found all through the body after the body has undergone development (Jurukovski, 2012). The adult stem cells multiply through division in order to replenish the cells that are dying as well as regenerating the tissues that have been damaged. These cells are also referred to as somatic stem cells and are found in juvenile and adult animals as well as human bodies. The ability of the adult stem cells to divide or have an indefinite self–renewal has gathers great interest in science. The cells have been suggested ...

Stem cell research

Stem Cell Research

Stem cells comprise natural in the human body capable of differentiating into different specialized cells (Cummings, 2009). These cells are also capable of self-renewal whereby they reproduce into more stem cells. Mammals produce two types; adult and embryonic stem cells. Embryonic stem cells are harvested from the inner cell mass of embryos in the blastocyst stage. Embryo cells differentiate into all the organs and tissues that form the human body. Adult stem cells are present in various tissues within the body (Cummings, 2009). These cells are responsible for body repairs and replenishment.

Stem cell research has been termed by the medical research fraternity as one of the greatest milestones in human health science. Stem cells can be defined as any kind of cell that can divide through mitosis and thereby specialize into any of the several different kinds of cells found in the human body. This specialization of the cells into any of the functional cell in the body means that doctors can use it to heal many cell-associated diseases. For example, there diseases and condition that lead to the damage of the neural cells in the brain or the spinal ...

Stem cell research has been termed by several health practitioners and scholars as one of the greatest milestones in medical research. Stem cells can be defined as any cells that have the ability to divide and thus can be specialized into any of the different kinds of cells found in the body . Such specialization and growth of cells into any of the functional cells implies that physicians can use the technology to cure many cell-related diseases. For instance, stem cells can be used to replace damaged cells due to cancer. Other diseases may lead to the damaging and degradation ...

Ethics of Stem Cell Research

Stem cells are central to newly developed therapies for curing degenerative diseases in humans. This is attributed to a very attractive feature of stem cells: their ability to produce a wide variety of other types of cells. Starting from stem cells, it is possible therefore to produce blood, brain, liver, muscle or essentially any type of specialized cell in a process called differentiation. Accordingly, with these therapies is now possible to aspire to find solutions to conditions that require organ or tissue replacement with a reduced rejection probability or even immune response (Juengst E). Patients with conditions like cirrhosis, muscle paralysis, corneal deterioration, ...

‘Stem cells’ is one of the widely discussed topics in recent years. Scientific progress led to the understanding the mechanism of stem cells and their use in therapeutic applications, which involve the treatment of cancer, diseases related to heart, brain and many others . Stem cells are a distinct type of cells, which are capable of regenerating themselves through the process of cell division. Under experimental conditions, stem cells have the ability to transform into tissue-specific or organ-specific cells. Since stem cells are unspecialized cells, they are capable of producing specialized cells through the process of differentiation . While embryonic stem cells ...

Stem cells is biologically fundamental structures found in all multi cellular organisms. These cells divide through the process of mitosis. Moreover, they possess a characteristic of dividing into more specialized cells and can also form more stem cells. Mammals possess two main types of stem cells. These include the progenitor cells and the embryonic stem cells. Another fundamental category of the stem cells includes the adult stem cells. All these kinds of stem cells possess specific kinds of characteristics and functions. The progenitor cells as well as the adult cells provide a repairing function in the bodies of adults. In addition, ...

Stem Cells

Stem cells are cells that have the potential to multiply and differentiate into numerous different cell types of the body during early life and growth. They also act as a form of internal repair system in many tissues where they divide without limit to replace other cells during the lifetime of a person or animal. In this paper, the unique properties of stem cells, different types, and differences between these types of stem cells, and potential application of stem cells will be explored. Stem cells are distinguishable from other cell types by 3 essential attributes: they are capable of proliferating ...

Introduction

There was a time when USA was far ahead of its competitors in innovation but in recent times the trend has seen a steep decline. Not only in innovation, America is also falling behind other countries in the area of high skilled workers literate in math, science and technology. There was a time, not long ago, when "the United States set the pace as the world’s leading innovator: from the personal computer to the internet, from Wall Street to Hollywood, from the decoding of the genome to the emergence of Web 2.0" but slowly it is "losing its innovation edge" (Kao ...

Stem Cell Research and Ethical Thinking

There has been a lot of debate surrounding embryonic stem cell research for quite a long time. The progress of stem cell science has slowed down because of the controversy. The main issues that have tormented the progress of stem cell research have been addressed and the ethical fault lines that will probably continue have been identified in the article “Update: Stem-Cell Research” ("Update: Stem-cell research," 2007). Although the restrictions on federal funding for embryonic stem cell research have been removed by President Obama, this article takes a look back and explores the factors that led President Bush to “ban all federal ...

However, detailed experimentation and examination of stem cells started in the United States ...

Stem cells are undifferentiated biological cells that can differentiate into specialized cells and further divide through the process of mitosis to produce more cells. Stem cells are found in multicellular organisms; however, in mammals there are two broad categories adult stem cells that are found in diverse tissues, and embryonic stem cells that are isolated from the inner cell mass of the blastocyst. Stem cells and progenitor cells act as a system that repairs the body in case it is injured as well as replenishing tissues (Humber 105). However, in the developing embryo stems cells differentiate into specialized cells that ...

Following the American Psychological Association’s Guidelines

Abstract Stem cell cloning is one of the biggest advancements the scientific and medical community has ever seen. Despite this amazing discovery, many individuals are finding ethical issues with the act of creating embryos for stem cell harvesting. Some may find this hard to believe because stem cells have the potential to help so many people that are suffering. Ethical issues include religious problems such as the unnatural formation of life, and its disposal, as well as the potential to clone humans. While many believe that cloning humans would eventually prove an ethical disaster, it is clear that ...

Introduction Embryonic scientific research offers optimism for innovative therapies, but their research has always been debated. Various countries regulate such research in different ways as the subject still carries a divided opinion. What makes the topic of use of embryos so tricky to resolve, and is it so tough to resolve the issues? The research use of human embryos is currently a high ethical and political agenda in many countries. Despite the possible benefit of the research, their use is contentious because they are derived from early embryos. In this essay, some of the ethical issues surrounding the use of human ...

Introduction

Stem cells refer to a group of undifferentiated cells that have the potential to develop or renew into different cell types. These cells come from two main sources, that is, the adult stem cells and embryonic stem cells. On the other hand, stem cell research focuses on scientific developments, scientists are taking to restore, reshape or grow cells. Stem cell research is a topic that generates debate in many places because it involves the use of science on cells. Some people consider this research as morally wrong while others important. This paper will critically evaluate both sides of the controversy. Moreover, ...

In the recent case brought up on appeal, U.S.A. vs Regenerative Sciences LLC, the Appellate Court re-examined the issue of whether federal laws regulating the manufacture and labeling of drugs and biological products were violated by a company that produced a mixture of stem cells and antibiotic doxycycline. In an earlier ruling, the District Court held that Regenerative Sciences LLC did violate these laws, and the Appellate Court affirmed the lower court’s judgment. This case received a lot of publicity due to the ethical issues surrounding stem cell research and resulting impacts to stakeholders affected by the outcome. The case presents ...

Introduction

Annotated bibliography Over the years there has been unending debate of whether the state should use federal funding to support the field of stem cell research or whether stem cell research should be allowed at all. According to Goodwin, This debate which has been looming on for centuries brings our thinking to the ethical question of biotechnological research and the moral use of human organs – the basic fundamental cells of life such as the stem cell. Those supporting the research and even those corporations funding it have proposed their support throwing weight on the fact that unused frozen ...

What is the evidence that convinces you Cancer Stem Cells are a subpopulation of tumour cells with distinct tumour‐initiating capacity? What are cancer stem cells (CSCs)? They are cancer cells that have similar characteristics as normal stem cells. CSCs have the potential to give rise to other cells types, and thus are tumorigenic in nature. These cells can generate tumors via stem cell processes of self-renewal, as well as differentiation into different cells (Wang, Chiou & Wu, 2013). CSCs have been found to persist in tumors in the form of a district population and often cause relapse and metastasis ...

Stem cells can be referred to as undifferentiated biological cells, which can form specialized cell when they differentiate and have the ability to divide to form more stem cells. Research scientists have discovered a number of potential applications of the stem cells. For instance, mesenchymal stem cells are presently being tried as a potential treatment for graft versus host disease as well as graft rejection. This is after trials on a number of animals demonstrating that treatments with allogenic stem cell were not rejected and demonstrated no difference in capabilities to heal as compared to autologous stem cells. This possibility is under ...

Overview of egg stem cells

Abstract Currently, the ability of a woman to produce eggs is limited by the age of the woman and the quality of the eggs that the older women produce. The research that was done about stem egg cells can address the issues of age and quality of eggs. Egg stem cells are eggs that are able to differentiate, or develop to other types of cells of the human being. There are possibilities that the new discoveries of egg stem cells is that they could be used and developed into new eggs. Even if this is not a possibility they could ...

During the last part of the 20th century, the science community began to do things that only a few years before would have been unimaginable. Since 1981 when embryonic stem cells were first isolated from mouse embryos research in molecular biology involving embryonic stems cells has moved quickly, and just as quickly ethic concerned having a background in Christian religious doctrine has fueled a strongly polarized debate as to whether or not such research is ethical. Research in this area has led to accomplishments such as cloned sheep and offers a novel way to treat disease. Previously in the United States there ...

The heart is one of the vital organs in a human body. This is the organ that determines the functionality of the other organism through supply of nutrients and oxygen, and removal of waste products from the body. Once the organ is affected or becomes ineffective, the individual will suffer a number of problems encompassing all the body system. One of the worst heart problems that an individual may develop is congestive heart failure (CHF). The condition renders heart muscles incapacitated to pump blood to the rest of the body. Ideally, the problem start from one side of the heart (left ...

Novel Stem Cell technologies (Isolation & Differentiation)

Stem cell technologies are now much easier to isolate and differentiate when compared to years ago. This paper shows those cells to have great plasticity with potential therapeutic application. Isolation and differentiation characteristics of those stems cells were considered to be on properties of the mesenchymal stem cells to be able to adhere to plastic surfaces. The importance of this research is that of the understanding of the properties of the stem cells and what make them function the way they were. Understanding that is being provided by this would represent a stepping stone for future advancement regarding more ...

Keywords : Gene therapy, Sickle Cell Anemia, Stem cells, lentivirus, β-globin

Project type: GBE-492 Genetic Engineering Project I. INTRODUCTION, BACKGROUND and AIM Sickle cell anemia is a devastating genetic disease which causes premature death. Sickle cell disease (SCD) is caused due to single amino acid change (glutamine to valine at position 6) in β chain of hemoglobin molecule, which causes the hemoglobin molecules to aggregate. These aggregated hemoglobin molecules make the red blood cells (RBCs) stiff and deformed (sickle shaped). These deformed cells block the normal blood flow. Although this disease is well-characterized, but no long-term treatment 1 is still available for this disease. The discovery of the sickle ...

Stem cells are primitive cells capable of forming distinct types of tissue. Due to the remarkable quality, human stem cells are depicted to hold incredible for the development of various therapies to regenerate organs that are damaged as well healing suffering from terrible diseases. Embryonic stem cells are usually derived from human embryos. Their use is relatively controversial since such stem cells are in capacity to be harvested from bone marrow and umbilical cord blood, as well as other adult tissues without harm to the other. `Detailed research regarding adult stem cells is not yet intense and is still a ...

The advancement of technology has precipitated a revolution in scientific understanding over the last several decades. Advancements in research tools has led to new insights into every facet of scientific discovery within the realms of chemistry, physics, and biology and all the sub-disciplines forming their constitution. Increased discovery has brought with it opportunities for cross discipline cooperation which has resulted in the formation of new disciplines and has galvanized scientists to press the boundaries of research and application as has never been seen in human history. One such field testing those limits is genetics. Today’s geneticists have expanded beyond ...

Why do you think there are an insufficient number of students interested in math, science, tech and engineering fields? What can the country do to correct this situation? Most of the students are not good in math in high school as a result of which they are disinterested in pursuing STEM (science, technology, engineering and math) in higher studies. Math aptitude as determined by SAT scores and high school grades is a necessity for a student to show interest in STEM. The factor of low marks and tough class schedules is another reason for students to opt out of STEM. ...

Embryonic stem cells are non-differentiated cells derived from developing embryos (blastocyst stage). This means a stem cell can give rise to any type of cell, such as a muscle cell or nerve cell. They are also very long-lived and self-sustaining. These cells are of particular interest to scientists because they have incredible potential in treating conditions such as cancer, Parkinson’s disease, and juvenile diabetes just to name a few (Thomson, 1998). However, these cells are harvested from embryos developed by in vitro fertilization (egg and sperm are united outside the body in a laboratory). These embryos are donated for research by couples ...

Abstract

The number of people being affected by various diseases that require them to have organ transplants increases every day. Meanwhile, the amount of donated organs is extremely insufficient to meet the high demand. There is also the problem of finding a donor match for a recipient and the need to take strong medications that suppress the immune system of the recipient so that the transplanted organ is not rejected. A solution to these problems has been and is still being developed, with laboratory-grown organs holding much promise. These organs can be tailor-made using the patient’s own cells or other cell sources, ...

PROPOSITION 71 - CALIFORNIA STEM CELL

Introduction Proposition 71 refers to the 2004 law that was passed by the people of California to permit the conduct of research on stem cells in the state (Baker, 2004). This proposition followed several years of the former United States President George Bush’s administration, which had prohibited the conduct of research on stem cells in California. Consequently, the law brought dissimilar changes to both the constitution of the state of California as well as the fitness and safety regulations of the state. Most importantly, the act has been codified in the Californian constitution as article xxxv (Baker, ...

Shaped tube electrolytic machining

Several methods have been employed to drill holes. Most of the time only mechanical methods have been thought up. These mechanical methods have a lot of disadvantages. Some of them being production of heat while drilling and also there was use of a lot of energy. Moreover, to drill both small and large holes is very difficult especially in hard and brittle materials using traditional drilling methods (Robert, H. & Allen, D, 1994). In some areas such as space, automobile, electronic sand computer (printed circuit boards), medical (Surgical implants), optics and miniature manufacturing provide the need for drilling holes in hard ...

Stem cell therapy nowadays has become a great subject for the medical research work.

A prolonged debate has been going on since many years over its applicability and rate of success. - INTRODUCTION It is believed that the embryonic stem cell has the capability to generate any organ in the body, it could be brain, heart, pancreas or any other organ that is diseased or needs to be repaired after significant degeneration, specially the ones which lacks the ability of regenerating on their own. Due to this ability of the embryonic cells they are also called as pluripotent cells. The embryonic cell is the cell which is formed right after conception ...

Abstract

Researchers have been faced with difficult moments in the past in their attempt to find a cure for HIV/AIDS. The trend that the virus takes in the human body is complicated since it stiches itself with the DNA of the host cells hence becoming part of the person. The way to eliminate or remove it from the human body without altering or killing the patient is very complex and it has not been achieved yet. However, some experiments and treatments that involve the use of therapy and stem cells transplantation have proved to be the way forward towards the eradication ...

THESIS: “To benefit our economy and society, our national priority should be on encouraging more students to study STEM” (Adkins) that includes science, technology, engineering, and math.

Our economy and society need new generation of new technology innovators, however the number of STEM students has shrunk dramatically.

5% of U.S. workforce is employed in STEM related fields but they provide more than 50% of the country’s sustained economic expansion.

STEM-related disciplines can serve for the universal betterment of society.

Once the U.S. was the residence of high-qualified STEM experts, but today the number of them sharply decreased.

The urgent need to encourage students to study STEM requires taking some measures.

The size of the STEM education may be increased by maintaining an enthusiasm for studying science, technology, engineering and math among the high school or college students.

Public-private partnerships can also be of particular importance because students will be taught both theory and practice.

The composition of the ...

Human embryo stem cell research is an emerging field in medical science which has raised serious ethical issues. It is still a matter of debate whether or not this technique should be employed for the research purpose and what would be the end result of the embryo. Since the research process has advanced a lot, the prime focus at the present time is not to decide whether or not it should be done but to determine ways to maintain the privacy. The government looked into the matter of human stem cell research because those derived from animal sources had potential ...

Despite decades of effort and a diversity of treatments, cancer is still a disease with poor prognosis. The cancer stem cell theory substantiates this fact that cancer cells have the ability to influence the growth and spread of tumor. It further states that a cancer stem cell can produce other cancer cells. This is because it withstands death due to its inability to undergo complex mitotic processes. This theory hypothesizes its findings based on tumor growth driven by rare subpopulation of cells. The cancer stem cell theory explains the fundamental force behind cancer by investigating its self renewal and cellular differentiation within ...
